How we work across the region
SEG’s head office, workshop and fleet are at SEG House in Chiswell Green, St Albans. Our engineers are employed, NICEIC-registered and supervised from there, so a job in Hertfordshire gets the same certification, photographs and paperwork as one down the road. Larger programmes are planned around the engineers’ routes, which is why we can stay competitive across the region.
